Hear The Koenigsegg One:1’s 1,340-HP Engine Start Up And Rev: Video

Koenigsegg’s new One:1 supercar is the most powerful production car ever built. Its twin-turbocharged 5.0-liter V-8 engine delivers a claimed 1,000 kilowatts, which equates to 1,341 horsepower or 1,360 horses if you’re into using metric figures. Peak torque, meanwhile, is an equally incredible 1,011 pound-feet, the bulk of which is produced below 3,000 rpm.

By comparison, the Bugatti Veyron Super Sport is producing a substantially lower 1,183 horsepower, and the current crop of hybrid supercars from Ferrari, McLaren and Porsche don’t even come close, with the most powerful of the trio, the LaFerrari, making do with ‘only’ 950 horsepower.

Thanks to this video from YouTube user GTBoard, we now know what the One:1’s monster of an engine sounds like when it’s started up and revved. Note, at present the One:1 remains a prototype. It’s about to start a lengthy testing phase before the six production units are finally assembled, so the sound you’re hearing is not indicative of the final result.

By the way, that sexy exhaust pipe you’re staring into is a custom titanium piece that Koenigsegg manufactures using a 3D printer... be sure to turn your volume up loud before you hit play!
